> we were able to achieve an energy density of 191.7 joules per cubic centimeter

Which is still quite a bit lower than

https://en.wikipedia.org/wiki/Lithium-ion_battery

> 900–2,490 J/cm3

And I don't see anything here about self-discharge rates, which are a big limitation for using capacitors for energy storage over any period of time. Does anyone know if the full study has that information?
worth looking into cathy wood's role in this respect. . .
I understand the product and the use cases. 90+% of people don't care about perf/watt, because it's an irrelevant implementation detail. People care about speed and autonomy.

The average user who is comparing this against a PC for AI stuff would prefer a faster PC with a (much!) larger battery and the same autonomy at the end of day in that task but that's much faster every time. If I need to do intensive enough on-device AI workloads for efficiency to matter and on battery, why would I take an iPad with a 30Wh battery, 2x perf/watt, and 1x speed over a laptop with a 65Wh battery, 1x perf/watt, and 10x speed? The latter will give me a better experience, it will be more responsive and last longer.

So at the end of the day, Apple's comparison is extremely misleading at best, and a straightforward lie at worst.
Javier Miles’s accomplishments so far as President of Argentina:

1) Inflation ⬇ 300% to 11%
2) The first quarterly budget surplus since 2008
3) interest rates cut three times
4) The Argentine peso is the world's best performing currency.
Plenty of people bought Teslas anticipating that they'd buy FSD when it fully worked "next year".
"Wartime paddleboards" is not a phrase I ever expected to read.
This is great. I'd love to see a higher level architectural writeup/talk (but not stack specific) about how to build a live search RAG system like this, perplexity, etc.
Moving out the allocations/releases out the hot path seems too much like a GC. Also, not all programs can be easily optimized moving the allocations: databases are an example, usually you don't know how much rows are you going to touch until you process the query.
This isn't about wages. This is about maintaining job security. Any kind of automation which promises less labor and/or less time is interpreted as "we dont need as many people as we did before." This is how a union person views these things - job killers.
Yes, thanks for calling that out. In verifying my statement I actually was confused because you can see they filter NMR out of the eval set (saying so explicitly) but don't say that in the test set section (IMHO they should be required to publish the actual selection script so we can inspect the results).
The logical consequence is to put all scientific publications under a license that restricts the right to train commercial ai models on them.

Science advances because of an open exchange of ideas, the original idea of patents was to grant the inventor exclusive use in exchange for disclosure of knowledge.

Those who did not patent, had to accept that their inventions would be studied and reverse engineered.

The „as a service“ model, breaks that approach.
15 years ago fang devs were some of the best. Now it feels like all of fang is crumbling under tech debt and enshittifying executives, like AOL did.

The city planners here in Auburn should probably watch this.

They have a horrible habit of performing this kind of work during the worst possible times.

All of the college students will be gone for the summer and things will be nice and quiet. Then the students return and football season begins. Town becomes a mess. Then the City of Auburn start resurfacing roads or adding medians or additional lanes.

It's happened every year for the past 14 years that I've been a resident. It never fails. They always wait until school starts back before they begin any repairs.

A better analogy is "weather forecasting".
Spare me with this; one of Musk's very first major actions was removing an account he didn't like (and had previously committed to leaving alone! https://twitter.com/elonmusk/status/1589414958508691456) because it was tweeting publicly available ADS-B data his plane was broadcasting... and then went on a tear banning journalists tweeting about it. https://en.wikipedia.org/wiki/December_2022_Twitter_suspensi...
Google Wave was a pretty radical reimagining, but it was a little too far ahead of its time technologically and way too far ahead of its time conceptually.
Well what is the “solution” to ethnic cleansing if not for the perpetrators to desist (or perhaps be made to desist) from doing it? What a bizarre analogy.
Does it use AI?
Parsing is fun, but assuming a good baseline allocator arena allocation doesn’t get you a whole lot these days (maybe it’s better under a GC environment where tear down does not require a tree traversal?), especially if you’re able to lazily build the AST (this is what I did in JSC years ago).

I still feel that there’s a lot of practical parsing stuff that isn’t considered in academia which leads to a near constant preference for LALR and LR parser generators despite them being honestly worse than recursive descent in almost every important metric if you want to do anything at all other than producing a completely generic AST for known good data.
Upgrading to Windows 7 from XP on my netbook surprisingly ran a lot smoother, also fixed a driver issue I had with the audio. In general though I notice no changes to performance between Windows versions, partly because the system requirements for Windows is so tiny to begin with (since it's designed to run on even old laptops).
How much revenue has twitter lost since the layoffs? At least a 22% decrease. Which is enough to mean shareholders would have gotten more money if all the useless employees had continued executing their "useless" function.

And this is assuming 2024 is going well for twitter. I doubt it.
Ah TIL
Mentioned under point 3 in the piece.
When was the first time? This doesn't really pass the sanity test. Half of the staff merely has to be available? For firefighters or ambulance drivers, this kind of ratio might make sense.
Important caveat: it's only about 70% accurate. Why doesn't the press release say this explicitly? It seems intentionally misleading to only report accuracy relative to existing methods, which apparently are just not so good (30%, 50% in various settings).

"Status Games" is a great way to phrase it. So much space that used to be occupied by political discussion is now devoted to status signalling disguised as political discussion, and the disingenuous presentation that comes with it. People will loudly proclaim a moralistic stance on a massive-scale social issue that they have little to no control over purely to signal status to peers and avoid dealing with bothersome things they're avoiding in their own lives. It's a worrying trend.
I dont think they were referring to engineers per-se.

You'll always need pigs for breakfast. Chickens are the ones who are probably in BS roles.
Yeah this part bothered me. It's surprising if they really didn't immediately realize randomly looking at single bills was an impossible strategy.

Kind of an interesting problem. Complete sorting in a timely manner is basically not possible because of the physical reality of 100k pieces of paper. But maybe you can group the bills into 100 piles of "last 2 digits", so then for each lookup you "only" have to check 1000 bills. And then later, while searching a group, you can take the time to further sort them by the 3rd digit. I guess it also depends on how long you expect the contest to go on, i.e. how many lookups you will do.

Even with the simplified grouping strategy, let's be generous and assume it takes you 3 seconds to look at a bill, figure out what to do with it, and physically move it to the correct place. That's still 83 person-hours to do a single pass and put the bills into 100 groups for quicker lookup. With 2 people, that's 5 full 8 hour days of non-stop sorting.
What happened to your other idea?
I doubt X's employees are that much more productive anyways. Before Musk the feature rollout was slower than molasses, and post-Musk all we get are reactionary changes that make the website suck more for non-users. It would not surprise me to hear that now 1/3rd or 1/4th of Musk's retainers are coasting by on their 9-5.
Those employees weren't free. You have to subtract those costs to employ from the 22% to get a more realistic shareholder impact.
Interesting, it seems Apple knows they are up against the wall where there isn't really much more their devices NEED to do. The cases that Apple gives for using these devices incredible compute is very marginal. Their phones computers and iPads are fantastic and mainly limited by physics. I have basically one of everything, love it all, and do not feel constrained by the devices of the last 3-4 years. Vision and Watch still leave room for improvement, but those are small lines. Limited opportunity to innovate, hence the Vision being pushed to market without a real path forward for customer need/use. Very few people read about the latest iPad m4 and think "oh wow my current iPad cant do that..."

Curious what steps they will take, or if they shouldn't just continue returning large amounts of cash to shareholders.
LSTMs are a recurrent architecture for neural networks, meaning that your output depends both on your current input and your previous output. This is similar to how language works, as the next word in your sentence must fit both the idea you're trying to convey (your input) and the words you've said up until now (your previous output).

LSTMs where very popular for a while (I think the first good version of Google Translate used them) but they had two critical downsides: their performance went down with longer outputs, and they where a bit annoying to parallelize because computing the output for the 10th word required first computing the output of the previous 9 words - no way to use 10 parallel computers. The first problem was solved with Attention, a scaffolding method that prevented degradation over longer sequences. Eventually someone realized that Attention was doing most of the heavy lifting, built an attention-only network that could be easily parallelized (the Transformer), and LSTMs lost the top place.

Are xLSTMs better? On paper I'd say they could be - they seem to have a solid theory and good results. Will they dethrone Transformers? My guess is no, as it wouldn't be the first time that the "better" technology ends up losing against whatever is popular. Having said that, it is entirely possible that some inherently recurrent tasks like stock price prediction could get a boost from this technology and they may find their place.
There is a specified common C++ ABI that gcc, clang, Intel's proprietary compiler, and others use. It was originally developed for the Itanium processor but is now used by gcc and clang for everything. See

https://itanium-cxx-abi.github.io/cxx-abi/abi.html

Unfortunately this ABI didn't specify how __int128 (and other nonstandard types) are to be passed.

> Then it hit me… there was nothing “wrong”, the page accurately and reliably reflected the latest data, BUT it didn’t tell the user what it was doing, or why nothing had changed, or what it was “looking” for new data in the background.

Perhaps actually the problem was more fundamental. The page didn't tell the user that it was showing latest data. E.g. "Updated 2s ago".
Yes if you lose your keys you do have to get new certificates and if possible revoke the lost keys. Revoking certificates will require either a revocation code that is issued when you get the certificate or you can use a copy of your private key to issue a revocation request.

If you don't have a revocation code or a private key for the cert you wish to revoke, it will require administrative access to the certificate registry to mark the cert as revoked. That feature is currently built into the platform but not something accessible because of the obvious challenges.

Your private keys are only known to you, certificate revocation is just an annotation that says to someone who receives a signature associated with that certificate to not trust the certificate.

All private keys are generated and stored only on your device.
> Musk, by contrast, never claimed to have something that he did not have.

IIRC, wasn't the video that claimed to demonstrate a full trip conducted by FSD actually like 100 different splices? That right there would be a claim of something that didn't exist.
Poisonous snakes everywhere. What’s a good alternative to Signal?
Your implementation strategy sounds interesting! I'll give it a try. While reading your design it made me interested if i as a user could prompt new indexes for libaries i use.

Ie if the quality RAG index is your primary offering, then as a user i imagine my experience will depend on how well you have indexed things i care about. Maybe my language of choice (Rust) has decent indexes, but some random Crate i try to use might not.

I'd love to be able to queue up index ingests of standard API sources like docs.rs/crates.io and be notified when that ingest completes.

Will give it a try today, congrats on the launch!

Very polished. Would love to know more about the tech behind this.
I asked a friend of mine who is chemistry professor at a large research university something along these lines a while ago. He said that so far these models don't work well in regions where either theory or data is scarce, which is where most progress happens. So he felt that until they can start making progress in those areas it won't change things much.
The OpenRail Association
This is exactly how the physicists felt at the dawn of quantum physics - the loss of meaningful human inquiry to blindly effective statistics. Sobering stuff…

Personally, I’m convinced that human reason is less pure than we think it to be, and that the move to large mathematical models might just be formalizing a lack-of-control that was always there. But that’s less of a philosophy of science discussion and more of a cognitive science one
There's not that many banks. FDIC says 4,587 [1], and I think NCUA numbers are similar. And the vast majority of them don't have new account promotions. But yeah, if you have a clean chexsystem report and this is what you spend your time on, you too can become a bank promotion thousandaire. Credit card promotions seem more common, and have the benefit that they're usually distributed as a discount so they tend not to be taxable, unlike bank promotions that are usually distributed as interest. OTOH, getting lots of credit card promotions tends to require lots of spending, real or manufactured, and manufactured spending tends to be difficult to manage at high levels. If you have a job / business that involves a lot of credit card spending, it can be easy to make the credit card promotions work, but if you have that kind of job, you might make more money spending more time on work than spending more time seeking credit card promotions.

I mean, who among us wouldn't watch 6 months of television with all of our spare time and take a bus from Ohio to LA for $331,381.55 in cash and prizes? (Roughly adjusted for inflation)

After all, it made for gripping television that is still being talked about today, they didn't lose on the exchange.
This is a cool toy, I've been wanting to do something similar with my flipper zero to make a BT morse keyboard.

This also reminds me of TapXR, which I would totally buy if did morse, instead of inventing their own encoding. I get it, theirs is probably way faster but fluency is morse is more general purpose.
I don't trust NMR structures in nearly all cases. The reasons are complex enough that I don't think it's worthwhile to discuss on Hacker News.
Yes, unless you’re in a niche area or only hiring through a network, you’re going to sift through mountains of unqualified candidates because those are mostly the ones on the market (see Market for Lemons[0])

Depending on your expected value of quantum computing, the Nobel committee shouldn't wait too long.
It's about revenue recognition. TSLA has beaten estimates multiple times based on revenue recognized from FSD "Beta". There's your fraud.
As always when this comes up, I ask about schools. Every single school system that has tried 4 day school weeks has had poor outcomes across the board. Children do worst academically and they fair worst socially, since that one less day is one less day that at risk children have access to either safety or food in some cases.

We can't ask teachers to work 5 days when the rest of the world doesn't. I'd also be interested in how much of the value some people are pulling from 4 day work weeks is just having a kid-free day to accomplish things. Would the value for care takers (who would make up a significant amount of young people) the same if their children accompanied them?

I don't really have an opinion on the 4 day work week, but I do think it's important to consider impact from all angles. I just never see the question of children come up in this conversation, although we know from covid that anything that impacts how children do anything in a systematic way has huge impact good or bad.

Sad. These guys are really cute. They’ll invite themselves to live in beaver dams and make for a vaguely tolerated roommate that helps patch up walls and stuff. They’re not as good at the big picture stuff as beavers.
Pulleys and knots can go hand in hand.

With ropes you can start with a basic loop that acts as a pulley. Butterfly, wireman's loop, farmers something - I forget the names.

But you basically create a loop that let's you double back your rope. With a lot of modern rope they are slippery enough you get pretty good mechanical advantage. Some folks then go to a taught line hitch or something to even keep things adjustable basically. Key is usually to give yourself enough space to tighten, and I skip the taughtline hitch in most cases.
If you can store new code, you can get a more optimized dictionary for what you are doing, though? Why not?
>You could avoid the scraping by requiring login

This is easily bypassed by having some sort of pattern matching sign-up script (because realistically, everyone is going to be using an off-the-shelf solution like wordpresss which you can detect and write scripts for) and paying a captcha solving farm to solve any captchas for you. Practically speaking though, having a signup wall is going to be killer for getting visits. It's already hard enough as it is to get started as an independent writer/blogger with no sign up wall. If you're going to force people to log in as well all that will do is ensure your posts are read by no one.

>or maybe having some continuously generated AI noise requiring social context filter out that a scraper wouldn't have (e.g. a bot in a chatroom that spews garbage that everyone knows to put in their killfile).

Similar problem to the above. Why would someone want to join your community when the first thing they see is that it has a spam problem that's seemingly unaddressed?
Yes, financial activism can have quite the wide ripple if you piss off the wrong big city liberals by taking away their ability to remove entire stories from the internet in direct cooperation with un-elected portions of the government.

Edit: We tech types are so predictable it's almost trite. Sorry I don't agree with your well-meaning technocracy and disingenuous moralistic posturing.
To offer personal advice, I come back to my belief that grandparents are the winners of the game of life. I would say that you should try to keep that in mind and not get too wrapped up in any particular status game, whether on social media or elsewhere, if it is going to take you off course.

Says the guy who runs a popular blog and whose station at life confers a fair amount of individual status. Sorry, but I would say someone like Elon Musk is a bigger winner at life than your typical grandparent. If who is a winner is broadened to include include almost anyone or everyone, the term loses its meaning. Being a winner implies some sort of exclusivity. It means beating out those who achieve or have less. This whole redefining winners to dilute its exclusivity is just another version of the participation trophy, but for the 'right', just as the left has its own versions of the trophy. Those seems to be most dismissive of status also have a lot of it, it would seem.
Maybe not necessarily "faster" but there is an idea that adding any kind of technology should be avoided for recreational activities. For example, you can mountain bike with a fully-suspended e-bike, or you can struggle with a hardtail or even a road bike. Different kinds of fun, but in the former you'll wonder if it's the technology doing all the work.
Productizing cost optimization experience! Great to see more options in this space, as so many companies are surprised by the costs of cloud.

For the warehouse size experimentation, how do you value processing time?
> Processing data at the edge also makes for the best possible user experience because of the complete independence of network connectivity and hence minimal latency.

I know a shop who's doing this and it's a very promising approach. The ability to offload the costs of cloud GPU time is a tremendous advantage. That's to say nothing of the decreased latency, increased privacy, etc. The glaring downside is that you are dependent upon your users to be willing and able to run native apps (or possibly WASM, I'm not sure) on bleeding edge hardware. However, for some target markets (e.g. video production, photography, designers, etc.) it's a "safe" assumption that they will be using the latest and greatest Macs.

I've also been hearing people talk somewhat seriously about setting up their own training/inference farms using Macs because, at least for now, they're more readily available and cheaper to buy/run than big GPUs. That comes with a host of ops problems but it still may prove worthwhile for some use cases and addresses some of the same privacy concerns as edge computing if you're able to keep data/computation in-house.
We'll be adding mobile support soon.
Whats the difference between a software engineer and a programmer? One of them has a job
Not to mention the value. Went from 55 to what 15 billion? Maybe 10? I don't think the cost cutting of a few hundred people making 6 figures makes that worth it.
